Traduction de «réservoir non récupérable » (Français → Anglais) :

2. With effect from the date on which Stage II petrol vapour recovery systems become mandatory pursuant to Article 3, where the recovered petrol vapour is transferred to a storage tank at the service station, the vapour/petrol ratio shall be equal to or greater than 0,95 but less than or equal to 1,05.

Existing service stations may need to adapt existing infrastructure and it is preferable to install vapour recovery equipment when they undergo major refurbishment of the fuelling system (that is to say, significant alteration or renewal of the station infrastructure, particularly tanks and pipes), since this significantly reduces the cost of the necessary adaptations.

As these tanks are new and have not previously contained petrol, no vapour will be displaced therefore the significant additional cost of vapour recovery equipment would not reduce the VOC emissions at all.

(j) 'vapour-recovery unit` shall mean equipment for the recovery of petrol from vapours including any buffer reservoir systems at a terminal;

(m) 'intermediate storage of vapours` shall mean the intermediate storage of vapours in a fixed roof tank at a terminal for later transfer to and recovery at another terminal.

Alberta's oil reserves are sourced in the following ways: by strip mining shallow bitumen sands deposits, where 90% recovery of original oil-in-place is achieved; by in situ extraction of bitumen sands in deeper deposits using cyclic steam stimulation, now achieving recovery factors of 35% to 40%; by steam-assisted gravity drainage, typically achieving recovery factors exceeding 50%, and sometimes up to 70%; by in situ extraction of bitumen carbonate deposits, where two successful commercial-scale pilot projects in the Grosmont deposit are now both proceeding to full scale-development; and by multiple fracking of horizontal wells in tight oil shales containing a large oil resource little developed as yet, but classed as “prov ...[+++]ed undeveloped”, based on success exploiting analogous tight oil shales in the U.S. These recent developments and improvements in recovery factors indicate Alberta's proved oil reserves are 848 billion barrels.
